The Pacific Tsunami Warning Center is indicating that a tsunami was indeed generated, and that possible tsunami waves could strike Matapalo, Quepos, and other areas of Costa Rica’s Pacific coast, as well as San Juan del Sur in Nicaragua.

The “watch” alert, which is less imminent than a “warning,” indicates that tsunami waves could reach Costa Rica between 10:40pm and 1:40am local time (GMT -6, or U.S. Mountain Time).

The head of the National Emergency Commission, Walter Fonseca, said there are currently no evacuation orders for any of Costa Rica’s coastal communities, and that more information would be available around 9:30pm local time as any potential tsunami were to arrive closer to the country.
